Methods of enhanced oil recovery are conducted after natural depletion to increase production. Polymer flooding by increasing water viscosity and decreasing mobility ratio cause to increase sweeping efficiency of the reservoir and ultimately enhances oil recovery. Polymer flooding is a commercial enhanced oil recovery (EOR) method used to increase the sweep efficiency of water floods by reduction in water fingering and break through that makes less CAPEX and OPEX cost. In this study, based on experimental work the polymer properties were tuned by adding the optimum amount on Nano clay. The results of experimental studies showed that considerable improvement in polymer properties will be achieved by adding Nano clay in specified amount to fixed concentration of polymer. The talk will present novel results relating to simulation studies i.e. natural depletion, water flooding and polymer flooding it has been shown that the polymer flooding scenario will produce the highest oil recovery with the lowest water produce and the lowest pressure drop, so it is proposed for Enhanced oil recovery
